Many times data visualizations need to communicate insights clearly and effectively. But sometimes the goals of a visualization go beyond that: they need to inspire and engage people. But how do you draw them in? What is the process behind creating a creative data visualization? During this talk, I will show some of my projects, and explain a little about the process behind it.

A discussion about making full-featured, commercial games in python, both 2D and 3D. Looking at state of the art approaches to using python in gaming, we will compare the alternatives: pygame (2D API), OpenGL (via pygame/pySDL2), Unreal Engine 4 and the Godot Engine (with further comparison to Unity 3D game engine). We will also look at other benefits of using python in the gaming context, such as integration with 3D modelling software, scripting the asset pipeline and GIS data integration....

High-energy particles accelerated by the Sun during Coronal Mass Ejections (CME) are a major concern for a manned mission to Mars. On Earth surface, these particles are shielded by the Earth magnetic field. In space and on the Martian surface, where such shielding is absent or much weaker, CME pose a radiation hazard to the health of astronauts. The development of tools to understand and forecast the interplanetary space weather is a requirement for future manned space missions in order to...

Despite 12 years of history and wide popularity the workings of Git still remain largely a mystery for many.

Introspection is often seen as a bad coding practice and as such a gadget. Nevertheless, the Python Standard Library provides different tools (among them the 'inspect' library) to easily identify a generator, recover the source code of a function or get a function signature. We propose to spend 1/2 hour to dig into what introspection has to offer to developers, to see what tools are available, what you can get out of them and some useful use cases that we met in our practice at Criteo.

Damn it, this can’t be happening! As programmers, we find ourselves time and again spiralling down into tighter loops of desperate troubleshooting, fighting the controls of our machinery and descending into what feels like a kind of madness. Later, when it’s all over, we realise that the clues we needed to recover the situation were staring us in the face all along, but we somehow couldn’t even see them.

Imagine you have some streaming computations running on a server. Client programs subscribe to real-time updates, so that they may visualise the computations for end users. How do you share this constantly changing server state with all connected clients? Sending an entire snapshot after each change is very inefficient, so you must implement some sort of incremental updates – diffs. But how do you generate these diffs on the server? And how do you represent them so the clients know how to...
